TOBACCO-PIPE.

T 0 all whom it may concern:

Be it known that I, JOHN BEVERLEY MAO- LAUGHLIN, of the city of Ottawa,in the Province of Ontario, Canada, have invented certain new and usefulImprovements in Tobacco-Pipes, of which the following is aspecification.

My invention relates to improvements in tobacco pipes and the objects ofmy inven tion are to prevent the nicotin pulling through the stem, andfurther to provide such a construction of an ordinary pipe that willenable a very cool smoke to be obtained, and which will avoid burning ofthe mouth of the smoker; and it consists essentially of a pipe having acenter bore doubled on itself to cause the smoke to first pass from thebowl toward the mouth piece, then backwardly toward the bowl, thentoward the mouth piece, said double portion being conveniently retainedin a suitable center section of the stem, all as hereinafter more fullyset forth and described in the accompanying specification and drawings.

In the drawings: F igurel is a longitudinal sectional perspective viewof a pipe constructed in accordance with the present invention. Fig. 2is a perspective view of the central section. Fig. 3 is a section on theline 2-2, Fig. 1. Fig. 4 is a section on the line 3-3, Fig. 3. Fig. 5 isa perspective view of a connecting member which may be employed toconnect the bore and the central section.

In the drawings like figures of reference indicate corresponding partsin each figure.

Referring to the drawings A represents the bowl and B the mouth piece ofusual form, which are connected, in accordance with the presentinvention, by an intermediate section 0 which is detachably connected tothe mouth piece and bowl in any suitable way, the connection of which tothe mouth piece is effected by means of a tubular connecting member20countersunk in both the intermediate section and the mouth piece, andthe connection to the mouth piece being effected by a screw-threadedtubular con necting member 21 engaged with suitable screw threadedrecesses on both the intermediate section and the mouth piece, saidintermediate section having flat faces 22 and 23 formed at the endadapted to abut corresponding faces formed on the stem and bowl section,the bowl having a portion of the stem 24 formed thereon of substantiallySpecification of Letters Patent.

the same cross-section as the intermediate section 0.

It will be noted that the tubular connecting member 20 is so located asto constitute an eccentric pivot upon which the stem portion B, may beswung around into position to expose the transverse channels 15 topermit of the same being cleaned without the necessity of entirelydisconnecting the parts and that the member 21 forms an eccentric pivotupon which the intermediate section may be swung clear of the bowl. Thiscentral section is characterized by having a plurality of bores thereinconnected in such a way that the smoke will be forced to passsuccessively through them. In the embodiment illustrated, three bores orpassageways 10, 11 and 12 are provided, the passageway 10 being adaptedto communicate with the passageway 13 leading from the bowl of the pipe,and the passageway 12 being adapted to communicate with the pasageway 14in the mouthpiece. The passageways 10 and 12 connect the passageway 11insuch a way that the smoke will be forced to pass through thepassageway 11 on its way from the passageway 10 to the passage way 12.This is accomplished by providing countersunk transverse channels 15connecting opposite ends of the passageway 11 with the passageways 10and 12 respectively.

It will be noted that the three bores 10, 11 and 12 extend completelythrough the intermediate section and so may be very conveniently formedtherein. The transverse channels 15 are formed just at the extreme endof the section so that the outer side of the channels will be closed bythe abutting faces 16 and 17 of the bowl and the mouth piecerespectively.

As a further precaution to prevent any chance of leakage at thesepoints, U-shaped tubular connecting members 18 may be inserted, but itwill be understood that their use is not absolutely necessary. as thejoint formed by the connection of the intermediate section with the bowland mouthpiece would generally be suflicient to prevent any leakage.

It will be noted that when the sections are separated, the transversechannels 15 and 16 are freely exposed and the passages may be veryreadily cleaned by blowing therethrough.

As many changes could be made in the above construction and manyapparently ter contained in the accompanying specification and drawingsshall be interpreted as illustrative and not in a limiting sense.

What I claim as my invention is:

A tobacco pipe comprising a bowl section formed with a bowl and shortstem leading therefrom formed with a flat outer face, a mouth pieceformed with a bare and flat inner face, an intermediate section havingflat'faces adapted to abut the flat faces on the bowl section and mouthpiece, and a tubular connecting member countersunk in the intermediatesection and bowl section and mouth piece respectively, and holding thesame together, the tubular members 20 and 21 connecting the intermediatesection to the stem section and bowl section respectively, beingeccentrically mounted in said section whereby the stem section may beswung around to expose said transverse grooves, and said intermediatesection swung clear of thebowl section without entirely disconnectingsaid parts, said intermediate section being formed with three bores, twoof which register with the mouth piece and bowl respectively, and thethird of which is connected with the other bores by countersunktransverse channels at the end in such a way that the smoke will passsuccessively through the three bores in the intermediate section, thebores in the bowl section and stem section respectively being ofsubstantially the same size as and forming continuations of one of thebores in said intermediate section, and said transverse channels beingadapted to be exposed when the mouth piece and bowl are separated.-

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
